Synthesis of Energetic Materials.
Abstract
The synthesis of polyformals from several nitro- and fluorodiols was investigated. Linear, difunctional polyformals were obtained from 3, 3, 5, 7, 7-pentanitro-5-azanonanediol, 3, 5, 5, 7-tetranitro-3, 7-diazanonanediol, 2, 2, 3, 3, 4, 4-hexa fluoropentanediol, and 2, 2, 3, 3, 4, 4, 5, 5-octafluorohexanediol. Procedures are given to prepare stable gumstocks from the first 3 of these, using FEFO as plasticizer. The fourth polymer was only partially miscible with FEFO. Efforts toward the synthesis of polyazabicyclooctanes and polyazaoxabicyclononanes were continued. An acyclic model compound for the latter system was synthesized and found to be marginally stable. Various approaches to the synthesis of azacyclooctadienes as precursers to bicyclononanes were investigated. A study of the chemistry of the 2, 6,-diazabicyclooctane ring system was iniatiated. Condensation reactions of 2, 3-disubstituted and 2, 3, 5, 6-tetrasubstituted 1, 4-dinitropiperazines with methylene diamine derivatives were investigated in efforts to prepare linear polycyclic nitramines. During this work, the first example of a 1,2-dinitramninoolefin was prepared. A new oxidizer of exceptionally high oxygen content, 2, 3, 5, 6-tetranitrato-1, 4-dinitropiperazine, was prepared but was found to decompose slowly at room temperature. Originator supplied keywords include: Nitrodiols; Polyformals; Nitropolymers; Nitramines; Diazocines; Azabicyclononanes; Azaadamantanes.
